摘要
LTE快速部署与站址资源不足之间的矛盾已经成为网络建设和优化中需要重点解决的问题。扇区分裂技术可以有效地解决站址问题,提升覆盖区域的整体容量,但也对扇区分裂的边缘区域有较大的干扰。主要对LTE扇区分裂技术在同频部署中的覆盖、容量、干扰3个方面的问题进行分析,对LTE部署扇区分裂技术的可行性进行研究,并给出部署建议。
The contradiction between LTE rapid deployment and lack of site resources has become a problem to be solved in the network construction and optimization. Sector division technology can effectively solve site lacking problems,enhance the overall capacity of regional coverage,but also has a greater interference exists at the edge of the sector division area. It analyzes the coverage,capacity and interference of LTE sector technology in the co-frequency deployment,studies the feasibility of the deployment of the LTE system,and gives the deployment suggestions.
